How you will distinguish C_(2)H_(5)NH_(2) and C_(6)H_(5)NH_(2) ?

Arrange the following: (i) In decreasing order of the pK_(b) values: C_(2)H_(5)NH_(2),C_(6)H_(5)NHCH_(3),(C_(2)H_(5))_(2)NHandC_(6)H_(5)NH_(2) (ii) In increasing order of basic strength: C_(6)H_(5)NH_(2),C_(6)H_(5)N(CH_(3))_(2),(C_(2)H_(5))_(2)NH andCH_(3)NH_(2) (iii) In increasing order of basic strength: (a) Aniline, p-nitroaniline and p-toluidine (b) C_(6)H_(5)NH_(2),C_(6)H_(5)NHCH_(3),C_(6)H_(5)CH_(2)NH_(2) (iv) In decreasing order of basic strength in gas phase: C_(2)H_(5)NH_(2),(C_(2)H_(5))_(2)NH,(C_(2)H_(5))_(3)NandNH_(3) (v) In increasing order of boiling point: C_(2)H_(5)OH,(CH_(3))_(2)NH,C_(2)H_(5)NH_(2) (vi) In increasing order of solubility in water: C_(6)H_(5)NH_(2),(C_(2)H_(5))_(2)NH,C_(2)H_(5)NH_(2^.)

Arrange the following in increasing order of their basic strength: i) C_2 H_5 NH_2, C_6 H_5 NH_2, NH_3, C_6 H_5 CH_2 NH_2 and (C_2 H_5)_2 NH ii) C_2 H_5 NH_2, (C_2 H_5)_2 NH,(C_2 H_5)_3 N, C_6 H_5 NH_2 iii) CH_3 NH_2, (CH_3)_2 NH_4, (CH_3)_3 N, C_6 H_5 NH_2, C_6 H_5 CH_2 NH_2

Arrange the following in decreasing order of their basic strength : C_6H_5 NH_2, C_2H_5NH_2 (C_2H_5)_2NH,NH_3 in aqueous solution.
